SIGCHILD informs a parent that a child has died : if they were to do a
wait(), they would expect it to complete immediately, but it would
block. So that would be a bad idea I think.

gnuplot can fork(), then allow the parent to exit, leaving the child
continuing to run the same code in exactly the same state, but
detached.
